[Lazarus] Getting a Field list of a record

[Johann Spies]

I see TDataset has a method to get a list of fields. Is there something
similar for type: record?

Say for instance I want to check which fields of a record are empty, how
can I do it without having to specify each field manually?

Another example: If I want to compare two records of the same type to
determine which fields differ.  How do I do it and get only a list of the
fields involved?

Regards
Johann
